Lukia Xu is known for building the systems that allow the creator economy to function at scale. As a product leader, she has not only shaped the foundational measurement and monetization infrastructure of two of the world’s most influential social platforms, but has done so at a moment when the creator economy — now valued at over $480 billion globally — is redefining how brands and individuals connect. Her work sits at an intersection that most people never see: the technical and strategic layer that determines whether a creator gets paid, whether an advertiser can prove a campaign worked, and whether a platform earns enough trust to attract the investment that sustains it all.
Xu’s path into technology began not in Silicon Valley but at Peking University in Beijing, where she studied economics, and later at the University of Southern California, where she earned a Master’s in Communication. It was during this time that she developed a conviction that would shape her entire career: that platforms and infrastructure matter more than any single product feature, because they determine what is possible for everyone who builds on top of them. She joined ByteDance in 2018 as the first product manager on TikTok’s ads measurement team — at a time when TikTok was only beginning its global monetization journey — and immediately confronted the gap between what the platform needed to be taken seriously by advertisers and what it actually had.
The first problem was verification. Major brand advertisers like P&G and Unilever would not commit significant budgets to any platform that could not offer third-party viewability measurement — a standard that TikTok, as a new entrant, had not yet met. Xu identified that the IAB Tech Lab had recently introduced the Open Measurement SDK, a new industry standard that allowed a single integration to support all measurement vendors simultaneously, replacing the expensive and time-consuming server-to-server approach that competitors like Meta and SNAP were using. She led the technical integration, secured IAB certification for ByteDance — making TikTok one of the first Chinese platforms to achieve it — and in doing so, unlocked the enterprise brand budgets that the platform had not been able to access before.
But verification was only the beginning. Xu went on to design TikTok’s first-party Brand Lift Study system from scratch: a native in-feed survey experience, an automated A/B experimentation framework, and a full data pipeline integrated directly into TikTok Ads Manager. The system was built to run at no additional cost to advertisers — a deliberate decision that she believed was essential for adoption. It worked. Since launching, it has become an essential tool for the thousands of brand advertisers on the platform. Adweek covered the global rollout. Xu then redesigned TikTok’s underlying incrementality infrastructure, extending measurement for the first time to non-standard ad products that combined organic and paid traffic — a capability that remained unique in the industry. “Advertisers fund the creator economy,” she says. “If they can’t measure results, they pull back. My job has always been to build the systems that give them confidence to stay in.”
Her highest-profile work at TikTok came when she took ownership of Branded Mission, described by TechCrunch at its launch as an industry-first solution that fundamentally changed how brands partner with creators at scale. The product used machine learning to match advertisers with relevant creators, automated the entire workflow from invitation to payment, and integrated the resulting user-generated content directly into TikTok’s ads delivery system. Under Xu’s leadership, Branded Mission expanded into multiple international markets, and regularly engaged with a large number of creators. For creators, the impact was tangible: everyday users with modest follower counts had a genuine path to meaningful income, with payout ranging from hundreds to thousands. The product’s design — a genuine value exchange between brands, creators, and platform — is what Xu credits for its durability. “It only works because all three sides benefit. That alignment is difficult to engineer, but when you get it right, it compounds.”
Today, as a Staff Product Manager at Pinterest, Xu leads the company’s premium upper-funnel ad formats, including Premiere Spotlight, the flagship product critical to the company’s ads portfolio, which she owns end-to-end: strategy, format design, advertiser experience, pricing, and reporting. As she continues her journey at Pinterest, she is set to bring more impactful launches by maximizing Pinterest’s intent-driven environment.
Beyond her work at Pinterest, Xu has become a committed voice for the next generation of product and design professionals. She mentors through ADPList and serves as a mentor in AIGA New York’s Growth Programs, sharing the kind of direct, practical knowledge that she had to build on her own early in her career. She was recently admitted as a Fellow of Beta Fellowship, a selective innovator community whose alumni span senior professionals from Google, Amazon, Meta, and TikTok, and which evaluates applicants through an expert panel review process on the basis of demonstrated excellence and contributions to their field. For Xu, these commitments reflect the same philosophy that has guided her product work. “Infrastructure only matters if people can actually use it,” she says. “That’s true whether you’re talking about ads measurement systems or the kind of knowledge that helps someone build a career.”
